4 04 Keysight 81180B Arbitrary Waveform Generator - Data Sheet Overcome Your Test Challenges With the 81180B Arbitrary Waveform Generator Electronic devices continue to grow increasingly complex, and the demand for higher performance never ends. In addition, you are under pressure to reduce test times and tighten specifications. The complexity of modern wireless systems skyrockets when you use techniques like digital modulation that compress wireless data to use bandwidth more efficiently. Test accuracy and repeatability are critical. In radar applications, a higher range helps you detect targets further out, and increased accuracy helps you better track targets. is proportional to the length of a pulse, so parameters like pulse length and pulse repetition frequency influence the radar range and range resolution. You need to be able to verify the performance of your radar system. To meet these challenges, you need new test tools. Commercial off-the-shelf waveform packages are seldom available for devices under test used in aerospace and defense applications, so testing system performance is challenging. To test your DUTs to their limits, you need flexible stimulus generating capability for any signal you can imagine. New High-bandwidth, High-resolution Arbitrary Waveform Generator Helps You Test With Confidence The Keysight Technologies, Inc B arbitrary waveform generator provides 4.6 GSa/s, 2 GHz IQ modulation bandwidth and 12-bit vertical resolution for applications where waveform resolution is an issue. Data-centric warfare requires real-time data and video communication. Satellite designers are pushed to use bandwidth greater than 1 GHz bandwidth. In addition, these bandwidths need to be available at higher carrier frequencies up to 44 GHz. New emerging standards call for up conversion up to 60 GHz. These setups require a reliable and precise modulation source. Any signal distortion gets multiplied by each of the test instruments, making it difficult to pinpoint a DUT failure. When the foundation for your signals is more precise, your test results are more meaningful. You want to test your DUT, not the source. Figure 4. Spurious performance of 81180B

5 05 Keysight 81180B Arbitrary Waveform Generator - Data Sheet Use Models of 81180B In this setup, the 81180B is used as a 2-GHz IQ modulation source. The Keysight E8267D performance signal generator Option 016 is needed for the 2 GHz IQ modulation input. You can use markers in conjunction with the pulse modulation to suppress the signal in the pulse pauses. The markers don t reduce the number of bits, so using markers improves waveform resolution instead of reducing it. You can use the 81180B for generating direct RF signals up to 1.5 GHz with a good signal waveform resolution. Modulation BW up to 2 GHz RF up to 44 GHz I/Q data via LAN USB or GPIB Marker Out Pulse mod input Figure 5. 2 GHz IQ modulation 81180B Differential I/Q signals E8267D Opt. 016 RF/IF out I/Q data via LAN USB or GPIB RF up to 1.5 GHz Modulation BW = 1.5 GHz-carrier frequency RF/IF out 81180B Figure GHz direct RF carrier frequency Generate versatile waveforms An arbitrary waveform generator is ideal for generating multiple waveform formats, so you can achieve interoperability between terrestrial and space-based communication devices. In addition to the flexibility of an arbitrary waveform generator, the 81180B gives you unprecedented flexibility with respect to channels. The instrument can run either in uncoupled mode so both channels work independently or in coupled mode, either phase coherent or with a defined delay between them. You can couple two 2-channel instruments to form a 4-channel instrument to simulate multiple emitter or receivers, such as multiple aircraft, where each could be designated as a target. By synchronizing the channels, you simplify your test setup and align the frequency and phase of the signals.

7 07 Keysight 81180B Arbitrary Waveform Generator - Data Sheet Increase Your Signal Play Time With Advanced Sequencing The closer your test signals are to the real-world situation, the better your test results will be. A key requirement is long signal play time, which means you need a big memory. The 81180B offers the choice between two memory sizes: 16 MSa and 64 MSa. For the best memory usage, a sequencer helps you create versatile, unique signals. Keysight 81180B sequence example: 81180B advanced sequencing is a sequence of sequences. A sequence contains individually looped waveform segments - up to 16,000 segments can be combined in a sequence - up to 1,000 sequences possible Loop 1 time Loop 5,200 times Loop 1 time Loop 3,567 times Loop 317 times Loop 1 time Loop 45 times Loop 1 time Loop 33 times Figure 9. Keysight 81180B sequence example Loop 5 times With this powerful sequencer, you can easily set up communication between ground stations and airborne devices. After an initiation sequence, the signal can contain separate transmission sequences followed by different messages. Figure 10. Keysight 81180B sequence/segment control Input In advanced sequencing scenarios you can define steps, loops and conditional jumps of waveforms or waveform sequences. You can set up to 1 advanced sequences per channel. Each sequence contains up to 16,000 different segments. Up to 1,000 sequences are possible. In some applications it is important to change quickly between different waveforms to minimize reconfiguration time. The sequencer allows you to download different test setups into memory. It is possible to directly access the memory via a 8-bit and 9-pin external input, which accepts TTL signals. You can select up to 256 segments or sequences via this dynamic segment/sequence control input. It can act as a dynamic switch between the sequences and segments as well.

8 08 Keysight 81180B Arbitrary Waveform Generator - Data Sheet Create Complex Signals in a Variety of Software Environments You can easily set up simple waveforms like sine waves, pulses, or ramps from the front panel of the 81180B. Complex modulation or arbitrary waveforms require waveform creation tools to create realistic signals. Matlab LabVIEW Visual Studio plus IVI Foundation Figure 11. Keysight BenchLink Waveform Builder Pro 81199A Keysight Wideband Waveform Center You can choose between tools like MATLAB software, NI LabVIEW and Visual Studio with IVI or Keysight waveform creation tools like Keysight BenchLink Waveform Builder Pro and Keysight wideband waveform center.

The standard waveform parameters are programmable. Arbitrary waveform coordinates are downloaded and stored in memory segments. The arbitrary waveform parameters are programmable. Arbitrary waveforms are downloaded and stored in memory segments. The segments are arranged in a sequence table that step, loop, jump and nest on segments in a user-defined configuration. Conditional jump and nest pending an event signal. Same functionality as described for sequenced waveforms except sequences are arranged in the sequence table. A modulated waveform is calculated from a built-in library of modulation schemes. A pulse waveform is calculated and downloaded to the arbitrary waveform memory. Run mode Continuous Self armed Armed Triggered Normal mode Override mode Gated A selected output function shape is output continuously. No start commands are required to generate waveforms. The output dwells on dc level and waits for an enable command and then the output waveform is output continuously; an abort command turns off the waveform. A trigger signal activates a single-shot or counted burst of output waveforms and then the instrument waits for the next trigger signal. The first trigger signal activates the output; consecutive triggers are ignored for the duration of the output waveform. The first trigger signal activates the output; consecutive triggers restart the output waveform whether the current waveform has been completed or not. A waveform is output when a gate signal is asserted. The waveform is repeated until the gate signal is de-asserted. Last period is always completed. Standard waveforms General Standard waveform library Standard waveform control Waveforms are computed and generated every time a standard waveform is selected. Built-in, auto computed waveforms: sine, triangle, square, ramp, pulse, sink, exponential rise, exponential decay, Gaussian, noise and DC. The standard waveform parameters can be adjusted to specific requirements. The waveform is recomputed with each parameter change.
